4 sentry drones and 3 missile batteries at the warp in point. All aggro on warp in. You have to dispatch the drones to open the cargo can (disguised as a habitation module) and pick up the datachip needed for the mission. There are a bunch of other structures none of which dropped loot for me.

4 frigates (Caldari Navy) sat at WIP. All aggro immediately. After a short time reinforcements arrive - 9 more frigs which appear pretty much at combat range, These are not triggered by the initial force as far as I can see.

Several groups of ships, mixed force of Amarr and Caldari vessels.
9 frigs/destroyers at 15k range which all aggro on warp in. Approximately ten more frigs/destroyers in two loose groups plus two cruisers separately.
